Masked youths burned rubbish and set up roadblocks in a volatile Venezuelan border city on Monday, witnesses said, in the latest protest over the suspension of a referendum drive to remove socialist President Nicolas Maduro.
Several hundred students held demonstrations in San Cristobal, near Colombia. The city, a hotbed of anti-Maduro sentiment, was the site of the worst violence during protests two years ago that led to 43 deaths around the nation.
"We want freedom!" chanted the protesters, who closed several roads under the watch of police and troops.
